Detailed Description
Reference will now be made in detail to the exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, like numbers in different drawings represent the same or similar elements unless otherwise indicated. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present invention. Rather, they are merely examples of apparatus and methods consistent with certain aspects of the invention, as detailed in the appended claims.
The configuration information updating method can be applied to a configuration center in a distributed system cluster, wherein the distributed system cluster comprises at least one configuration center, at least one management node and two or more than two nodes connected with the management node.
Fig. 1 is a flowchart illustrating a configuration information updating method according to an exemplary embodiment, where, as shown in fig. 1, the configuration information updating method includes the following steps 100 and 104:
in step 100, a clock calibration script is used to calibrate the machine clocks of a plurality of nodes.
Here, the configuration center may calibrate its own machine clock first, and then calibrate the machine clock for all nodes under the management node by using the clock calibration script. For example, to ensure time accuracy, the machine clock of a node may be calibrated to the millisecond level. Compared with the common calibration method, the method has the advantages that the clock calibration script is adopted to calibrate the machine clocks of all the nodes in the distributed system cluster, so that the calibration efficiency and the calibration precision can be improved, and the updating efficiency of the configuration information can be improved.
Here, after the calibration of the machine clock is finished, all nodes send registration information to the configuration center to establish connection with the configuration center respectively, and the registration information may include a physical address, a port address, service information, and the like of the node.
In step 102, new configuration information is generated according to rule content, where the new configuration information includes configuration effective time, and the configuration effective time is used to indicate that the plurality of nodes replace original configuration information with the new configuration information when the machine clock reaches a preset time.
Here, since rule contents often need to be added or modified, when new rule contents need to be added or existing rule contents need to be partially modified, new configuration information needs to be generated for the addition or modification of the rule contents. Here, the configuration validation time is a time that can guarantee that all nodes acquire the new configuration information, and for example, the configuration validation time may be a specific time point, and may be, for example, "11 hours, 23 minutes, 50 seconds, 23 milliseconds", that is, when the time of the machine clock of the node reaches 11 hours, 23 minutes, 50 seconds, 23 milliseconds, the original configuration information is replaced with the new configuration information.
In step 104, a notification message is sent to the plurality of nodes, where the notification message is used to instruct the plurality of nodes to acquire the new configuration information.
For example, when the configuration center generates the configuration information with the configuration validation time, the notification information is sent to the node, and the node receives the notification information and then pulls the generated new configuration information from the configuration center.
In this embodiment, a clock calibration script is used to calibrate machine clocks of multiple nodes, new configuration information is generated according to rule contents, and a notification message is sent to the multiple nodes, where the notification message is used to instruct the multiple nodes to acquire the new configuration information, the new configuration information includes configuration effective time, and the configuration effective time is used to instruct the multiple nodes to replace original configuration information with the new configuration information when the machine clocks reach preset time; the new configuration information of all the nodes can take effect at the same time after all the nodes obtain the new configuration information, so that the occurrence of an intermediate state is avoided, the consistency of the states of all the nodes during the updating of the configuration information is ensured, and meanwhile, the reliability during the updating of the configuration information is also ensured.
Fig. 2 is a flowchart illustrating a configuration information updating method according to an exemplary embodiment, as shown in fig. 2, in the configuration information updating method, before step 102, step 101 is further included, and step 102 may be executed as steps 1021 and 1022 and steps 1023 and 1025:
in step 101, it is determined whether the rule content has a historical configuration record.
Here, the historical configuration record refers to a record that the configuration center generates the historical configuration information according to the content of the historical rule and updates the generated historical configuration information to each node before the configuration information is updated, and specifically includes a time point when the configuration information starts to be generated and a time point when the configuration information is successfully generated, a time point when each node successfully pulls the historical configuration information from the configuration center, and the like. Here, the historical rule content refers to a rule content that can obtain the current rule content through modification of partial content, for example, when the configuration center has generated first configuration information according to the first rule content and has successfully updated the first configuration information to each node, and after that, when a certain parameter in the first rule content is changed, the configuration center takes the first rule content with the changed certain parameter as the current rule content, the first rule content is the historical rule content, and the first configuration information is the historical configuration information. Before generating new configuration information according to the current rule content, the configuration center needs to judge whether a historical configuration record of the first rule content exists, so that the historical configuration record of the first rule content is used as a data reference.
In step 1021, when there is no historical configuration record in the rule content, generating configuration information according to the rule content;
in step 1022, a first configuration validation time is set for the configuration information, where the first configuration validation time is a time generated by a sum of a generation time of the configuration information and a preset time duration.
Here, for the newly added rule content, since there is no historical configuration record, the configuration validation time may be directly set as the time generated by the sum of the generation time of the configuration information and the preset time duration, for example, according to the service statistics, the first preset time may be set to 500 milliseconds; thus, when the generation time of the configuration information is "11 hours 23 minutes 50 seconds 23 milliseconds", the first configuration validation time is "11 hours 23 minutes 50 seconds 523 milliseconds"
In step 1023, configuration information is generated according to the rule content when the rule content has a history configuration record.
In step 1024, according to the historical configuration record, the time required from the generation of the configuration information to the acquisition of the configuration information by the plurality of nodes is estimated.
Here, when there is a corresponding historical configuration record, the time length required from the generation of the configuration information to the acquisition of the configuration information by the plurality of nodes of this time may be estimated according to the generation time of the historical configuration information recorded by the historical configuration record and the time points at which the respective nodes respectively acquire the historical configuration information
In step 1025, a second configuration validation time is set for the configuration information, where the second configuration validation time is a time generated by a sum of a generation time and an estimated duration of the configuration information.
For example, when the generation time of the configuration information is "11 hours, 23 minutes, 50 seconds, 23 milliseconds", and the estimated time length is 300 milliseconds, the second configuration validation time is "11 hours, 23 minutes, 50 seconds, 323 milliseconds". For example, a buffer duration, for example, 10 ms, may be set, and the generation time of the configuration information, the estimated duration, and the buffer duration, and the sum of these three times, may be used as the second configuration validation time.
In this embodiment, when a corresponding historical configuration record exists in the rule content, according to the historical configuration record, a time required from generation of the configuration information to acquisition of the configuration information by the plurality of nodes is estimated, and a second configuration validation time is set for the generated configuration information, where the second configuration validation time is a time generated by a sum of a generation time of the configuration information and the estimated time, and the set configuration validation time can be more accurate, so that consistency of node states in a cluster and reliability of node data are further ensured.
Fig. 3 is a flowchart illustrating a configuration information updating method according to an exemplary embodiment, where as shown in fig. 3, the configuration information updating method further includes steps 106 and 114:
in step 106, N nodes are selected from the plurality of nodes, and for each node of the N nodes, a time required from the generation of the new configuration information to the acquisition of the new configuration information by the node is counted to obtain N time values, where N is an integer greater than or equal to 2.
Here, in the process of updating the configuration information, the configuration center records the generation time of the new configuration information, and respectively records the time point of receiving the new configuration information pull success message fed back by each node. Here, when the configuration center records that N nodes feed back a message that new configuration information is successfully pulled, according to the recorded generation time of the new configuration information and each time point when the N nodes successfully pull the new configuration information, the time duration required from the generation of the new configuration information to each node to acquire the new configuration information is respectively calculated, and N time duration values are obtained. Illustratively, N is a minimum of one-third the number of nodes in the distributed system cluster.
In step 108, the average value T of the N duration values is calculated
0。
Here, a minimum duration and a maximum duration may be removed and then an average value may be calculated to ensure the accuracy of the data.
In step 110, the formula T ═ T is adopted
s+T
0X, calculating the effective time T, T of the optimal configuration of the new configuration information
sAnd the time is the generation time of the new configuration information, X is a time coefficient, and X is more than or equal to 2.5 and less than or equal to 3.5.
Here, the time coefficient X is obtained from traffic statistics, and both timeliness and stability can be achieved. Compared with the estimation according to the historical configuration record, the estimation is performed according to the time length required by the partial nodes to acquire the configuration information, and the more accurate configuration effective time can be acquired. For example, when the configuration information is generated at time T
sIs "11 hours, 23 minutes, 50 seconds, 23 milliseconds", and the average value T
0200 ms, X is 3, and the second configuration effective time is "11 hours, 23 minutes, 50 seconds, 623 ms".
In step 112, the difference between the configuration effective time and the optimal configuration effective time is calculated.
In step 114, when the difference is greater than or equal to a preset threshold, replacing the configuration effective time with the optimal configuration effective time.
Here, if the optimal configuration time is very close to the configuration effective time preset previously, it indicates that the preset configuration effective time is very accurate and does not need to be corrected by using the optimal configuration effective time. For example, the preset threshold may be 5 milliseconds.
In this embodiment, the accuracy of the configuration effective time and the timeliness of the effective of the new configuration information can be ensured by calculating the optimal configuration effective time and correcting the preset configuration effective time by using the optimal configuration effective time.
Fig. 4 is a flowchart illustrating a configuration information updating method according to an exemplary embodiment, and as shown in fig. 4, the step 100 in the configuration information updating method further includes steps 201 and 204:
in step 201, physical addresses of the plurality of nodes are obtained.
In step 202, the physical address is saved in a memory list of the management node.
In step 203, for each node in the in-memory list, a network is connected to the node.
In step 204, the time of the machine clock of the node is made to be consistent with the network time through a preset Linux command.
Here, the clock calibration script may be stored in a user directory of the management node, all nodes under the management node are scanned by the clock calibration script, a physical address of each node is obtained, the obtained physical address of the node is stored in a memory list of the management node, a mechanical clock is calibrated for each node in the memory list, and a calibration result is returned after the calibration is completed, so as to generate subsequent new configuration information. For example, the clock calibration script may be used to perform multiple calibrations to ensure that all nodes are successfully calibrated.
FIG. 5 is a flow diagram illustrating a method for updating configuration information, such as
As shown in fig. 5, the step 204 of the configuration information updating method further includes steps 301-304:
in step 301, the historical configuration records are divided into Y times and M nodes are obtained each time.
In step 302, for each node in the M nodes, according to the historical configuration record, calculating a time length required from generation of historical configuration information to acquisition of the historical configuration information by the node, and obtaining M time length values, where Y and M are integers greater than or equal to 2.
In step 303, for each of the M duration values obtained, the maximum duration value is selected.
In step 304, an average value of the selected Y maximum duration values is calculated, and the average value is used as an estimated duration value required from the generation of the configuration information to the acquisition of the configuration information by the node.
